Example simple app that uses Human to process video input and
draw output on screen using internal draw helper functions

import Human from '@vladmandic/human';

// create instance of human with simple configuration using default values
const config = { backend: 'webgl' };
const human = new Human(config);

function detectVideo() {
  // select input HTMLVideoElement and output HTMLCanvasElement from page
  const inputVideo = document.getElementById('video-id');
  const outputCanvas = document.getElementById('canvas-id');
  // perform processing using default configuration
  human.detect(inputVideo).then((result) => {
    // result object will contain detected details
    // as well as the processed canvas itself
    // so lets first draw processed frame on canvas
    human.draw.canvas(result.canvas, outputCanvas);
    // then draw results on the same canvas
    human.draw.face(outputCanvas, result.face);
    human.draw.body(outputCanvas, result.body);
    human.draw.hand(outputCanvas, result.hand);
    human.draw.gesture(outputCanvas, result.gesture);
    // loop immediate to next frame
    requestAnimationFrame(detectVideo);
  });
}

detectVideo();

Default models

Default models in Human library are:

• Face Detection: MediaPipe BlazeFace-Back
• Face Mesh: MediaPipe FaceMesh
• Face Description: HSE FaceRes
• Face Iris Analysis: MediaPipe Iris
• Emotion Detection: Oarriaga Emotion
• Body Analysis: PoseNet

Note that alternative models are provided and can be enabled via configuration
For example, PoseNet model can be switched for BlazePose model depending on the use case

For more info, see Configuration Details and List of Models
